Definitions
- the disclosure relate to a circularly polarized luminescence material and application thereof, in particular to a central chirality induced spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex-based circularly polarized luminescence material and application thereof.
- Circularly polarized luminescence is a phenomenon that chiral luminescence materials are excited and emit left-handed or right-handed circularly polarized light. Therefore, design and development of chiral luminescence materials are the key to this field. With in-depth researches by researchers, circularly polarized luminescence materials exhibit important applications in 3D display, data storage, quantum computing, optical anti-counterfeiting, biological imaging and asymmetric synthesis so far.
- Cyclometalated platinum (II) and palladium (II) complex-based phosphorescent material can fully utilize all of singlet and triplet excitons generated by electroexcitation due to its heavy atom effect, so that its maximum theoretical quantum efficiency can be up to 100%, and thus such complex is an ideal luminescence material.
- Bidentate cyclometalated platinum (II) and palladium (II) complexes have relatively low rigidity, and its luminescent quantum efficiency is reduced due to a fact that two bidentate ligands are easy to twist and vibrate so that energy of material molecule with an excited state is consumed in a non-radiation mode (Inorg. Chem. 2002, 41, 3055).
- tridentate ligand-based cyclometalated platinum (II) and palladium (II) complexes can be with improved luminescence quantum efficiency due to enhanced molecular rigidity (Inorg. Chem. 2010, 49, 11276)
- a second unidentate ligand such as Cl ⁇ , phenoxy negative ions, alkyne negative ions, carbene and the like contained greatly reduces chemical stability and thermal stability of the complexes, which is difficult to sublimate and purify for preparation of OLED devices. Therefore, the luminescence material base on that bidentate and tridentate ligand-based cyclometalated complexes do not facilitate their application in stable and efficient OLED devices.
- Central metal ions of divalent cyclometalated platinum (II) and palladium (II) complexes are all dsp 2 hybridized, and are easy to coordinate with the tetradentate ligand to form stable and rigid molecules with a planar quadrilateral configuration.
- High molecular rigidity can inhibit nonradiative relaxation caused by molecular vibration and rotation, and reduce energy loss of material molecules with the excited state, thereby facilitating improving of the luminescent quantum efficiency of the material molecules.
- Due to steric hindrance of two aryl groups at an end of a tetradentate cyclometalated platinum (II) and palladium (II) complex material molecules exhibit a distorted quadrilateral configuration (Chem. Mater.
- a central chirality induced spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex-based circularly polarized luminescence material and application thereof are provided in this disclosure.
- Spiro chiral metal complex molecules can autonomously induce a whole tetradentate ligand to coordinate with metal ions in a less sterically hindered manner by means of a central chiral fragment L a in the tetradentate ligand, to form an optically pure spiro chiral metal complex-based circularly polarized luminescence material, without need for chiral resolution.

- the organic light emitting device is a 3D display device, a three-dimensional imaging device, an optical information encryption device, an information storage device, a biological imaging device, or the like.
- the disclosure includes following beneficial effects.
- the central chiral L a can independently induce the whole tetradentate ligand to coordinate with a metal ion in a less sterically hindered manner so as to form the optically pure spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex circularly polarized luminescence material with the metal ion as a center, as shown in FIG. 1 .
- Circularly polarized luminescence material of two corresponding optically pure chiral isomers of the spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex can be conveniently prepared from the two optically pure chiral tetradentate ligands, which greatly reduces preparation cost of the material without separation and purification through a chiral column.
- the designed and developed tetradentate ligand can well coordinate with dsp 2 hybridized platinum (II) and palladium (II) metal ions to form molecules with a stable and rigid quadrilateral configuration, with high chemical stability; meanwhile, since large steric hindrance effect exists between the designed central chiral ligand L a and the ligand L 1 or L b at another end, the metal complex molecule as a whole can form a stable spiro chiral tetradentate cyclometalated complex, so that the spiro chiral tetradentate cyclometalated complex can not be racemized and lose circularly polarized luminescence property in a solution or in a process of sublimation at a high temperature.

- FIG. 1 shows a design idea of an optically pure spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex circularly polarized luminescence material with metal ion as a center: the optically pure raw materials are economical and easy to be obtained; spiro chirality can be generated by autonomous induction of central chirality; there's no need for chiral resolution for the circularly polarized luminescence material, which greatly saves preparation cost of the optical pure materials, and the circularly polarized luminescence material can be prepared in a large amount and is not limited by resolution of a chiral preparation column.
- ligands containing central chirality can autonomously induce generation of M spiro chirality
- ligands containing central chirality can autonomously induce generation of P spiro chirality
- a M spiro chiral molecule and a P spiro chiral molecule are enantiomers to each other.
- the luminescent color of the tetradentate metal complex can be efficiently adjusted approximately by adjusting the structure of the tetradentate ligand, and adjustment from an ultraviolet region at about 360 nm to a red region at 650 nm can be achieved, and it is believed that infrared luminescence can also be achieved through further regulation of the tetradentate ligand structure.
- emission spectra from FIG. 6 to FIG. 20 are substantially completely coincident, which further proves that corresponding material molecules in the figures are enantiomers.
- FIGS. 26 to 33 are circularly polarized luminescence spectra of part of material molecules.
- the comparative material molecules PtON1, PtON3 and PtOO3 have no circularly polarized luminescence.
- the material has high chemical stability and thermal stability.
- the designed and developed tetradentate ligand can well coordinate with dsp 2 hybridized platinum (II) and palladium (II) metal ions to form molecules with a stable and rigid quadrilateral configuration, with high chemical stability; meanwhile, since large steric hindrance effect exists between the designed central chiral ligand L a and the ligand L 1 or L b at another end, the metal complex molecule as a whole can form a stable spiro chiral tetradentate cyclometalated complex, so that the spiro chiral tetradentate cyclometalated complex can not be racemized and lose circularly polarized luminescence property in a solution or in a process of sublimation at a high temperature.
